Unless you are in an industry in which Printed Circuit Boards (PCB's) are used on a regular basis, you might not know exactly what they are. A PCB is an independent module of electronic interconnects. The green boards you see inside your electroncis are PCB's. Their function is to provide the
Difference in “Electronics” and “Electrical”: Electronics deals with flow of charge (electron) through non-metal conductors (semi-conductors). Electrical deals with the flow of charge through metal
Surface mount components are small and can be mounted on either side of the PCB and have gained widespread usage in electronics. The benefits of SMT or Surface Mount Technology are available in both design and manufacturing.
Electrons are negatively charged and protons are positively charged while neutrons are neutrally charged. At the same time the number of electrons and protons in an atom is always same. Now, if, by any means, few electrons can move away from the atom of object A to atom of object B, then object A will get positively charged
Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, oscillator, wireless). Some of the main Electronic Components are: resistor, capacitor, transistor, diode, operational amplifier, resistor array, logic gate etc.
SMT (Surface Mount Technology) needs several types of equipment. Pick-and-Place machine is the heart of surface mount. A pick-and-place machine picks and places electronic components onto the PCB prior to soldering. These machines generally contribute to about 50% of the total cost of a complete SMT production line.
SMT (Surface Mount Technology), like other SMD Soldering and PCB assembly technology is not ZERO-Defect soldering process. There will always be some or the other defect in any Electronics PCB assembly in both Thru-Hole and SMT.
